How to copy material texture settings between faces
Following @moonboots' suggestion: If you  select all the faces to be mapped identically, and U unwrap them together, with the 'Reset' option, they will all be mapped to the full (0,0) > (1,1)  UV space. You can then line them all up together.

The shipped 'Magic UV' add-on collection also provides an option to copy and paste UVs, either between individual faces, or between ordered selections. if you copy > [default] a single face, you can then select  destination faces, and paste > [default] (N:M) the UVs into all of them.
